2.2 I Hydraulic connec ons
• Respect the direc on of hydraulic connec on (see § “1.3 I Dimensions and marking”).
• Choose the dimension of the pipes according to the size of the pool and respec ng the hydraulic rules which apply in
the country of installa on.
• Performance curves are available in § “1.4 I Performance curves” for the pipe dimensions.
• For hydraulic connec ons, use the Ø63/50 mm union couplings via bonding (provided) or the 2’’ threaded PVC
couplings directly screwed onto the pump.
• Fit a check valve if the fi lter is installed above the water level.
• Fit suc on and discharge isola on valves if the pump is installed below the water level.
• To help prevent diffi culty in priming, install the suc on pipe without high points, which can trap air.
• Check that the hydraulic correc ons are correctly ghtened and that there are no leaks.
• The pipes must be supported to prevent any risk of breakage due to the weight of the water.

• Use as few elbow joints as possible. If there needs to be more than 10 elbow joints on the hydraulic circuit, increase
the pipe diameter.
• Suc on pipe length = 4 x Ø
• Suc on pipe too short
• Risk of cavita on
• Air reten on
• Risk of incorrect pre- fi lter fi lling
